Reproduce random.choice() challenge generating a NameError


I'm getting "NameError: name 'random_item' is not defined." I'm not sure why.

# random_item("Treehouse")
# The randomly selected number is 4.
# The return value would be "h"
import random

str = "Kate"

def random_item(str):
        return str[random.randomint(0, len(items) -1)]

There are 3 main issues I can see.

  1. Indentation issue. There is an extra indent on your return
  2. Your randint method is misspelled. It should be randint not randomint.
  3. You are doing the len(items). It should be len(str) since you are checking the length of the argument provided in the function

Also, a word of caution on using str as a variable name or an argument. str() is a builtin function used to turn values into strings. Depending on how it is used, it could create odd behavior or even make things a little confusing when developers see it used in other places.
